Ireland, so good in the set-piece last weekend, concede a penalty at the scrum and miss the chance to apply some pressure on the Scots in their own half.

Jared Payne has already made quite an impression, he's got very impressive line speed and is getting right in the face of the Scottish attackers. 

Zebo thinks he's got Ireland flying down the left flank. But his pass to Luke Fitzgerald is messy, and Scotland win possession from the line-out and then a scrum in their own half from a knock-on.

Well, Scotland nick it at the line-out, Grant Gilchrist getting a hand in. Uncharacteristic from Ireland. Hugh Blake tries to get the legs going but is cut off.

A decently worked scrum in their own half from Scotland. They get up towards the halfway line but concede a penalty. Ireland go into touch and they will test that line-out which was so impressive against Wales last week. 

Zebo is once again under a high one, this time from Isaac Boss. Scotland with a scrum though after a knock on.

"Apart from the enormous honour, captaining your country is also an extra responsibility on your shoulders, so we'll see how Sean O'Brien gets on today."

A confident little spell for Ireland to begin with. The ball's moving quickly and Ian Madigan has already had a feel of the leather a couple of times.

Scotland get us under way and it's into the arms of Simon Zebo. We're off.

Joe Sugg has tweeted about going to Twickenham today. I'm told he's kind of a big deal. I honestly have no idea.

But he has 2.38 million followers on Twitter though.

"From a rangy kid with a flamboyant hairstyle to the level-headed kingpin."

Glasgow scrum-half Henry Pyrgos will wear the Scotland armband for the first time today.

Dorset-born, but into a family where "the Calcutta Cup was like Braveheart", Pyrgos has an interesting story.

Read about it here.

As we draw closer to kick-off at the Aviva Stadium, it would be remiss of us not to remind you that England take on France at 20:00 BST in their first World Cup warm-up of the summer. You can stay right here for all the action.

So many decisions for Stuart Lancaster...

A great day for Chris Henry today. Nine months ago the flanker underwent heart surgery, following the news he had a blocked blood vessel in his brain.

There were no guarantees he world play professional rugby again. Today he starts for Ireland for the first time since going into that operating theatre.

More than just a game and all that... bravo.

We want pictures of you in your rugby shirt. But try to look like you're having fun, yeah? Thanks.

It's not been a great year for Scotland, despite there being a sense of revival in the country's game. The last time they faced Ireland, in the Six Nations, they were on the end of a 40-10 tonking. It's five defeats from five for the Scots in 2015.  

As we know, Kevin Pietersen is right. About everything. Might as well just have the World Cup final now between New Zealand and Ireland and get it done and dusted.

Ireland head coach Joe Schmidt is talking to Sky Sports about what he wants today:

It's been a while since you were able to brush off your country's jersey and show your allegiance.
